"That's a clear violation of the Voter Protection Act," says Andrew Myers, after we reached him by phone and told him of the bill. "The worker protections are one of the most important features of the law."

Without the anti-discrimination part of the law, qualified users of medical marijuana could end up like Joseph Casias, a former Michigan Walmart employee, says Myers.

Casias, who was diagnosed with an inoperable brain tumor and sinus cancer, is qualified under Michigan law to use medical marijuana, (or, as anti-espanol Michigan calls it, marihuana). When he submitted to a drug test at work after twisting his knee, Walmart fired him when he came up positive for pot.

Myers also points out that the Voter Protection Act not only requires the three-quarter majority vote, but demands that any alteration to a voter-approved initiative must further "the purpose of the measure."
